The HK416 is an assault rifle designed and manufactured by Heckler & Koch. It is an improved version of the M4 carbine with many changes, most notably a new gas operating system from the G36.

The US Army's Delta Force collaborated with the German arms maker to develop the new carbine. Delta replaced its M4s with the HK416 in 2004 after tests revealed that the piston operating system significantly reduces malfunctions while increasing the life of parts.

The project was originally called the HK M4, but this was changed in response to a trademark infringement suit filed by Colt Defense. The weapon has been tested by the United States military and is in use with some law enforcement agencies and special operations units. It has been adopted as the standard rifle in two NATO nations as well.
